Introduction

During prenatal checkups, testing for hepatitis B surface antibody and hepatitis B surface antigen can determine whether a person is infected with the hepatitis B virus. A negative result for hepatitis B surface antibody indicates no infection, while a positive result for hepatitis B surface antigen indicates current hepatitis B virus infection. Therefore, testing for hepatitis B antibodies and antigens during prenatal examinations can effectively detect hepatitis B infection.

During prenatal checkups, testing for hepatitis B surface antibody and hepatitis B surface antigen can determine whether a person is infected with the hepatitis B virus.

A negative result for hepatitis B surface antibody indicates no infection with the hepatitis B virus, while a positive result for hepatitis B surface antigen indicates existing hepatitis B infection. Therefore, testing for hepatitis B antibodies and antigens during prenatal examinations can effectively detect hepatitis B.

Hepatitis B poses significant risks to both pregnant women and their fetuses. If a pregnant woman is infected, the virus can be transmitted to the fetus through the bloodstream. Additionally, if hepatitis B is not properly controlled during pregnancy, it may lead to excessive liver strain. During prenatal checkups, timely detection of hepatitis B allows, under medical guidance, prompt use of medications to block mother-to-child transmission, which plays a positive role in preventing fetal infection with the hepatitis B virus.

Hepatitis B is a disease that can be transmitted from mother to child and may seriously affect the infant's healthy development; therefore, preventive measures are essential. Pregnant women should follow their doctor's recommendations and undergo regular prenatal examinations to ensure the health and proper development of their baby. In daily life, they should pay attention to nutrition, emphasize intake of protein, vitamins, and minerals, get adequate rest, and avoid excessive fatigue.
